2018 Ram ProMaster engine

The DEF injection system and SCR catalyst
enable the achievement of diesel emissions
requirements; while maintaining outstanding
fuel economy, drivability, torque and power
ratings.
Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for
system messages and warnings.
NOTE:
• Your vehicle is equipped with a DEF injec-tion system. You may occasionally hear an
audible clicking noise from under the ve-
hicle at a stop. This is normal operation.
• The DEF pump will run for a period of time after engine shutdown to purge the DEF
system. This is normal operation and may
be audible from under the vehicle.
Adding Diesel Exhaust Fluid
NOTE:
Driving conditions (altitude, vehicle speed,
load, etc.) will effect the amount of DEF that
is used by your vehicle.
DEF Fill Procedure
NOTE:
Refer to “Fluids And Lubricants” in “Techni-
cal Specifications” for the correct fluid type.
CAUTION!
It is extremely important to avoid any con-
tamination of the diesel fuel with Diesel
Exhaust Fluid (DEF). Ensure that the die-
sel fuel filler cap is in place and com-
pletely tightened before opening or filling
the DEF.
1. Remove cap from DEF filler neck (located on drivers side of the vehicle in the fuel
door).
2. Insert DEF fill adapter/nozzle into DEF tank filler neck.
CAUTION!
•To avoid DEF spillage, and possible dam-
age to the DEF tank from overfilling, do
not “top off” the DEF tank after filling.
• DO NOT OVERFILL. DEF will freeze be- low 12ºF (-11ºC). The DEF system is
designed to work in temperatures below
the DEF freezing point, however, if the
tank is overfilled and freezes, the system
could be damaged.

CAUTION!
• When DEF is spilled, clean the areaimmediately with water and use an ab-
sorbent material to soak up the spills on
the ground.
• Do not attempt to start your engine if DEF is accidentally added to the diesel
fuel tank as it can result in severe dam-
age to your engine, including but not
limited to failure of the fuel pump and
injectors.
• Never add anything other than DEF to the tank – especially any form of hydro-
carbon such as diesel fuel, fuel system
additives, gasoline, or any other
petroleum-based product. Even a very
small amount of these, less than
100 parts per million or less than 1 oz.
per 78 gallons (295 liters) will contami-
nate the entire DEF system and will
require replacement. If owners use a
container, funnel or nozzle when refilling
the tank, it should either be new or one
that is has only been used for adding
DEF. Mopar provides an attachable
nozzle with its DEF for this purpose. 3. Stop filling the DEF tank immediately
when any of the following happen:
• DEF stops flowing from the fill bottle into the DEF tank.
• DEF splashes out the filler neck.
• DEF pump nozzle automatically shuts off.
4. Reinstall cap onto DEF filler neck.
Filling The Def Tank In Cold Climates
Since DEF will begin to freeze at 12°F
(-11°C), your vehicle is equipped with an
automatic DEF heating system. This allows
the DEF injection system to operate properly
at temperatures below 12°F (-11°C). If your
vehicle is not in operation for an extended
period of time with temperatures below 12°F
(-11°C), the DEF in the tank may freeze. If
the tank is overfilled and freezes, it could be
damaged. Therefore, do not overfill the DEF
tank.
Extra care should be taken when filling with
portable containers to avoid overfilling.

Recreational Towing — Gasoline
Engine All Models
Recreational towing is allowedONLYif the
front wheels are OFFthe ground. This may be
accomplished using a tow dolly or vehicle
trailer. If using a tow dolly, follow this proce-
dure:
1. Properly secure the dolly to the tow ve- hicle, following the dolly manufacturer's
instructions.
2. Drive the front wheels onto the tow dolly.
3. Firmly apply the parking brake. Place the transmission in PARK.
4. Properly secure the front wheels to the dolly, following the dolly manufacturer's
instructions.
5. Release the parking brake.
CAUTION!
• DO NOT flat tow this vehicle. Damage to the drivetrain will result. If this vehicle
requires towing, make sure the drive
wheels are OFF the ground.
• Towing this vehicle in violation of the
above requirements can cause severe
transmission damage. Damage from im-
proper towing is not covered under the
New Vehicle Limited Warranty.
Recreational Towing —
Diesel Engine All Models
NOTE:
Automated Manual transmission (diesel) ve-
hicles can also be flat towed (all four wheels
on the ground) with the transmission in NEU-
TRAL. Ensure the transmission is in neutral
(N) (by checking that the vehicle moves when
pushed) and tow in the same way as a normal
vehicle with a manual transmission.

FUSES
WARNING!
• When replacing a blown fuse, always usean appropriate replacement fuse with
the same amp rating as the original fuse.
Never replace a fuse with another fuse of
higher amp rating. Never replace a
blown fuse with metal wires or any other
material. Do not place a fuse inside a
circuit breaker cavity or vice versa. Fail-
ure to use proper fuses may result in
serious personal injury, fire and/or prop-
erty damage.
• Before replacing a fuse, make sure that
the ignition is off and that all the other
services are switched off and/or disen-
gaged.
WARNING!
• If the replaced fuse blows again, contactan authorized dealer.
• If a general protection fuse for safety
systems (air bag system, braking sys-
tem), power unit systems (engine sys-
tem, transmission system) or steering
system blows, contact an authorized
dealer.
